What is the area of the triangle?
A. 8.64 ft2
B. 10.8 ft2
C. 14.4 ft2
D. 17.28 ft2
Answer: 8.64
Step-by-step explanation:
3.6 * 4.8 = 17.28
17.82/2 = 8.64
Answer:
A. 8.64 ft²
Step-by-step explanation:
The equation for the area of a triangle is A = 1/2bh
b is base and in this case 4.8
h is height and in this case 3.6
A = 1/2 (3.6)(4.8)
A = 8.64

the product of the roots of a quadratic equation 2x²-5x+3=0 is 5/2 if it is correct give reason
9514 1404 393
Answer:
It is incorrect. The product is 3/2.
Step-by-step explanation:
The factored form of a quadratic with roots p and q can be ...
a(x -p)(x -q) = ax² -a(p+q) +apq
Then the product of the roots is the ratio of the constant to the leading coefficient:
pq = (apq)/a
In the given quadratic, that product is ...
pq = 3/2 . . . . . . not 5/2
The statement that the product of roots is 5/2 is incorrect. That value does not have the required relationship to the coefficients of the quadratic.

Step-by-step explanation:
A man in a tower spots three hot air balloons flying at the same altitude. Balloon
A is 5 miles east and 8 miles south of the
tower. Balloon B is 7 miles west and 10 miles
north of the tower. If Balloon C is located
four-ninths the distance from Balloon A to
Balloon B, find the location of Balloon C
relative to the tower.
Answer:
90/4= 12.9
1*3/4= 0.75
Step-by-step explanation:
The location of Balloon C is 0.13 miles relative to the tower.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Balloon A is 5 miles east and 8 miles south of the
tower.
Balloon B is 7 miles west and 10 miles north of the tower.
If Balloon C is located four-ninths the distance from Balloon A to Balloon B,
According to the question, AB distance is 21.64 miles
⇒ 21.64×4/9 = 9.61
⇒ 9.61 - 9.43 = 0.18
⇒ 0.18×7/10 = 0.13
Hence, the location of Balloon C is 0.13 miles relative to the tower.

Every day kianna practices softball and piano each day she practices for 2 hours if after 7 days she practiced both softball and piano for a total of 24.5 hours how many hours per day did kianna ptactice piano
Answer: 1.5 hours
Step-by-step explanation:
Softball was practiced for 2 hours each day.
After 7 days she must have practiced it for;
= 7 * 2
= 14 hours
She practiced both piano and softball for a total of 24.5 hours. She therefore practiced piano for;
= 24.5 - 14
= 10.5 hours
If in 7 days she practiced piano for 10.5 hours, everyday she must have practiced piano for;
= 10.5/7
= 1.5 hours

One angle is a complementary pair is twice as large as the other. What is the measure of the larger angle?
a. 30°
b. 60°
c. 90°
d. 120°
Answer:
60 degrees
Step-by-step explanation:LARGE ANGLE...60-degrees
So, we have x + 2x = 90. Solving for x, we get x = 30. Since the first angle was called x, that means it's measurement is 30°. The second angle, 2x, is just twice the first angle, so its measurement is 60°

Which describes dependent events?
drawing a blue marble and a yellow marble at the same time from a bag of marbles
drawing the ace of spades from a deck of cards, putting it back into the deck, and
drawing the king of spades.
rolling a six-sided number cube and getting an even number, then rolling the same six-sided number cube and getting an even number again
flipping two coins at the same time and getting heads on one and tails on the other
Answer: Drawing a blue marble and a yellow marble at the same time from a bag of marbles is the example of dependent events.
Step-by-step explanation: When the cards are replaced, or flipping coins or rolling dice, the outcome of the first event does nor affect the probability of the next event.
Drawing two marbles at the same time is essentially the same as drawing one and Not replacing it and then drawing the second one. The number of marbles left affects the probability.

The radius of a sphere is decreasing at a rate of 2 centimeters per second. At the instant when the radius of the sphere is 3 centimeters, what is the rate of change, in square centimeters per second, of the surface area of the sphere? (The surface area S of a sphere with radius r is S = 4πr2.)
Answer:
The rate of change of the surface area of the sphere is;
-48π cm^2/s
Step-by-step explanation:
Here, we want to calculate dA/dt
Mathematically that will be;
dA/dt = dA/dr * dr/dt
From the question;
dr/dt = -2 cm/s
dA/dr = 8πr
So dA/dt will be;
-2cm/s * 8πr = -16 πr cm/s where r is 3 cm
So;
dA/dt = -48π cm^2/s
Using implicit differentiation, it is found that the rate of change of the surface area of the sphere is of -151 square centimetres per second.
The surface area of an sphere of radius r is given by:
[tex]S = 4\pi r^2[/tex]
Applying implicit differentiation, the rate of change is given by:
[tex]S = 8\pi r\frac{dr}{dt}[/tex]
For this problem:
The radius of a sphere is decreasing at a rate of 2 centimetres per second, hence [tex]\frac{dr}{dt} = -2[/tex]It also is of 3 centimetres, hence [tex]r = 3[/tex]The rate of change is of:
[tex]S = 8\pi(3)(-2) = -48\pi = -151[/tex]
The rate of change of the surface area of the sphere is of -151 square centimetres per second.
